AUTOMATIC FLARE MACHINE.

Application led July 8,

To all whom it' may concer/n:

Be it known that we, FRANCIS J. RIPPL and FRANK J. MALLOY, citizens of the United States, residing at Cleveland, in the county of Cuyahoga, State of Ohio, have invented certain neu'1 and useful Improvements in Automatic Flare Machines, of which the following is a specification.

Our invention relates to lamp making machines and vmore particularly to automatic' machines for making iares for incandescent lamps.

Our object is to provide an automatic machine Jfor the production of flares from substantially long lengths of glass cylinders or tubing. In this specification, a flare will be understood to mean' a piece of glass stem tubing Aon which a flare has been formed.

Heretorore, flares have been made from glass tubing which has been cut to length before Hanging. An automatic machine for making flares is disclosed in Fagan Patent No. 866,347, September 17, 1907. However, in machines of this type, labor must be used to cut glass tubes of vproper length from glass tubing. The glass tubes must then vbe properly placed in a hopper Jfor feeding.

` to the automatic flare machine.

1n the machine embodying our invention, the uncut lengths of glass tubing are placed in suitable holding means and the ends of the tubing successively subjected to the various operations necessary to the proper flanging of the flare. The flare is then cut oi from the glass tubing'` in the proper lengths by an improved glass cutting means.

More specifically, we have provided a carrier containing a series lof suitable holding means for glass tubing and means for. rotating the glass tube holding means. In properl sequence in the path of the end of the Glass tubing, we have provided means v Y for eating the end of the tubing, means for flanging the from the tubing, and means for cutting the flare from Athe tubing.

We are enabled to use long lengths of glass tubing without previous preparation and to secure acomparatively high rate of production otfinished' flares with a very end of the tubing, means r for gauging the length of the flare to be cut 1921. Serial No. 488,334.

In general terms, the operation of the machine is as follows: A piece of glass tubing 10, Fig. 1, is placed in each of a series of rotating chucks A (see also Figs. 6 and 7) which are mounted on the carrier 11 more fully described hereinafter. The carrier 11 plan on the line is so driven that each of the chucks A is' intermittently advanced through a predetermined path in which a sequence of opera-l tions is performed upon the end of the glass tubing held in the chuck. Thus the glass tubing is rotated about its own axis by the chuck and about an external axis by the carriera' At the first position, or position B, Fig. l3, the tubing is given a preliminary heating in the predetermined zone of cut-off' by a gas burner 12. The tubing is then advanced to position C where it is further .heated locally by the gas burners 13. At position D, to which the tubing is now brought, an intensive heat is applied to the zone of cut-off by the gas burners 14.

The gas burner 15 heats the zone of cutoff at position E while the cutting oil' mechanism F (shown in Figs. 13 to 22', inclusive) removes a section of tubing from the lower end of the tubing 10. In the present machine, the section of tubing removed is a flare 16 (Fig. 1) suitable for use in the manufacture of. incandescentv lamps. The flare 16 is 'discharged into a vibrating chute F C (Fig. 3) which delivers it to a suitable container.

The tubing 10 is now advanced to the position G where an intensive heat is applied to the lower end of the tubing by the gas burners 19, Fig. 3. The tubing is then they Vshaft 31 isA moved to position where it is further heated by the gas burners 20 while beinffand is advanced to position B Where a repel tition of the cycle just described" is begun.

The drive of the machine is effected by the motbr 21 (Figs. 1 and 2) which is mounted in the base 22. The motor 21 through a belt'23 drives the countershaft 24 which is also mounted in the base 22. The countershaft 24 through the belt 25 drives the main driving shaft 26 (Figs. 3 and 4) which is suitably supported on the brackets 27 and 28 in the b ase 22. 'A safety connection is provided between the belt and the'main driving shaft 26 to prevent injury to the machine as a whole should any of the mechanisms become jammed. This connection consists of the gear 29 (Figs. 3, 4 and 5) fastened to the shaft 26 and rotatably carried on the shaft 26 a pulley 29l which is driven by the belt 25. Inserted xin the lug 29D on the hub extension of the pulley 29a is hardened steel plug 29c which has a slot 29d therein for receiving a soft steel bar 29 held in place by the set screw 29f. The gear 29 v has a hardened steel plug 29g, similar to the plug 29, inserted in the hub thereof so as to receive the soft steel bar 29B in a slot 29h. When the pulley 29a-is driven by the belt 25, the soft steel bar 29e causes thegear 29,

and the attached shaft 26 to be rotated under ordinary .circumstances However, should any of the operating mechanisms become jammed, the driving means tends to stall and puts a greater burden upon the soft steel bar 29e which is thereupon sheared i between the edges of the hardened steel plugs 29 and 29g automatically relieving the strain upon the operating mechanisms and the driving means by permitting the pulley 29a to be freely rotated upon the shaft 26. The

safety connection is again placed into operative condition by removing the broken steel bar 29e and inserting a new-one in lits place.

The gear 29, fastenedto the main shaft 26, meshes with al gear 30 (Figs. 2, 6 and 8) fastened to the intermediate shaft 31 which is supported from the base 22 by the brackets 32 and 33. To the inner end of fastened'a bevel gear 34 (Fig. 6) which meshes with and drives the bevel gear 35 (Figs. 6-and 9) fastened to the lower end of the vertical shaft 36 which is rotatably supported in the tubular shaft transmitted through cn I 37. To the upper end of the shaft 36 is fastened a large gear 38 (Fig. 6) which meshes with and drives each chuck A as more fully described hereinafter. The tubular shaft 37 is suitably supported in the base 22 and the column 39 `mounted thereon and' has fastened to its up-per end the carrier 11 previously mentioned. The tubular shaft 37 n and carrier 11 are indexed by means of a; Geneva gear 40 (Figs. ,6, 9 and 11) which is attached to the lower end of the shaft 37 and which has a locking disc 41 fastened to its upper side. The Geneva ear 40 is driven by the Geneva. pinion 42 O L(Figs. 9, 10 and 11) which is fastened to the vertical shaft 43 suitably lmounted in the support 44 fastened to the under side of the b-ase 22.v A gear 45, rotatablyheld on the shaft 43 and continuously driven by the Gear 46 fastened to the vertical shaft 36,

drives the Geneva pinion 42 through the clutch 47 which slides on the shaft 43 and which is connected to the Geneva pinion 42 by a pin 48 fastened in the pinion 42 and working in a-.recess 49 in the clutch-47. A recess 50 in the .clutch 47 is intermittently brought into engagement with a pin 51 fastened to the gear 45, in order to drive the Geneva pinion 42, by the action of the cam 52 fastened to the cam shaft 53 suitably supported by brackets fastened to the base 22 Vand driven fromv the intermediate shaft 31 by the gear 54 (see Figs'. 2, 3 and 6,) thereon which drives'the gear 55 on the cam shaft 53 through the idler gear 54 mounted on the shaft .55 carried in the base 22. `The action of the cam 52. (Figs. 9 and ^10) is p the lever 56 which is pinned at 57 to the bracket 58 .and which has pinnned near the middle thereof a roller 59 whichA rides on the cam 52. The lower end of the lever 56 ispinned to a link 60 whose other end is connected to a lever 61 fastened to the shaft 62 carried in the support 44. To the shaft 62 is fastened ai yoke 63 which engages a groove 64 in the clutch 47 so as to control the vertical position of the clutch on the shaft 43. A spring 65 fastened to the link 60 vand to the base 22' tends to hold theroller 59 against the cam 52. 'llhe outline of the cam 52 is such that o-nce every revolution thereof the lever 56 swings in toward the cam 52 and, through the link 60, lever 61, shaft 62 and yoke\63, forces the clutch.- 47 downward so that the recess 56therein engagesrthe pini 51 on the yeontinuoi'isly rotating gear45 to drive for one revolution thereof the clutch 47l and, through the pint48, the Geneva. pinion 42 which in turn' drives the Geneva gear 49. The Geneva gear 40 ythrough the ltubular shaft 37 to the upper end Vof which is attached the carrier 11 advances the chucks A mounted thereon through an angle suiiicient to move them from-one position to the sucgear 45 receives the thrust of the clutch 47 when it engages with the gear' 45.

In order to insure the stopping of the carrier 11 with the chucks A in the exact predetermined positions for the several steps of the operation as previously described, the

locking disc 41, previously mentioned, is attached to the upper surface of the Geneva gear 40 (Figs. 9, 10 and 11) and has a series of notches 69 in the periphery thereof corresponding to the number of positions on the machine. One of these notches 69 is engaged by the vnose 70 on one arm of a crank 71 mounted on the pin 72 fastened in. the support 44. A spring 73 fastened to the other arm of the crank 71 and to the support 44 tends to hold the nose `70 in engagement with a notch 69. As the Geneva pinion 42'begins to engage the Geneva gear 40 for the rotation thereof, the nose 70 is removed from engagement with th notch 69 by a cam-like projection 74, fastened to the. Geneva pinion 42, which strikes a projection .(see also Fig. 12) fastened in an arm of the crank 71 so that the crank 71 is lforced away from the locking disc 41. As

soon as the Geneva gear 40 and attached locking disc 41 have been rotated by the .Geneva pinion v42 through an angle suiiciently large to `prevent the engagement of the nose 70 with the notch 69 which it has 'ust released, the projection 74 on the pin- 1on 42 releases the projection 75 on the crank 71 thus permitting the crank 71 to re- Aturnv toward the locking disc- 41 bringing the nose 70 into position to engage vthe succeeding noh 69 as it is ,rotated into place. The projection 75 may be adj usted'to change the relative time at which it is engaged by the projection 74 by adjusting the screw 7 6- Fig. 12) which is seated in the projection 75 and which` screws into the hub of the crank 71. When properly adjusted the proection 75l is fastened into place by the bolt 7 which passes through a slot 7 8 in the pro-f jection 75 and screws into an arnf of the crank 71. l

@uiting off mecmsmf-As previously 1 tubing V10 'with the describe/d', the glass flange on the lowerend thereofis heated on the line of the glass tubing 1() and mechanism FB eut-0E in the positions B, C and `D and alsov in the cutting-olf position E (see (Figs. 16, 17, 18 and 19) for performing the actual cutting voff of the iiare in the preheated zone. Brieiy, the operatlon iscar- .ried out as follows: The gauged and lowered glass tube 10, which has previously been flanged and preheated in the zone of of cut off. The cutting mechanisml FB then operates to cut the tubing 10 leaving the flare F10 (Fig. 1) in the chuck FA. Thereupon the chuck FA releases the flare F111' which is discharged into a chute FG which delivers it to a suitable container. In order to simplify the description, each part of the mechanism will be described separately giving the drive the letter F of the cutting off mechanism as a whole; the tubing holding means or chuck,'theC letters FA; the means for cutting the tubing, the letters FB;v and the delivery-chute, the letters FG; in each case the proper letters being coupled with suitable numerals.

rlhe cutting off mechanism drive is effected from the main drivin# shaft 26 by a bevel gear F11 (Figs. 4 anv 13) attached thereto which meshes with and drives a bevel gear F12 (Fig. 13)'fastened-to the vertical shaft F12 which has suitable bearings in the housing F11 and the bracket F15 to which the housing F11 is attached.v The bracket F15 is fastened to the base 22. A gear F16 (Figs. 13, 16 and 18) rotatably held on the upper end of the shaft F12 is normally caused to rotate therewith by the friction clutch F11 fastened to the shaft F12 so as to drive the chuck FA as described hereinafter (Fig. 18). rlihe'clutch F11 has a leather faced disc`F18' driven by a pin F19 fastened inthe clutch and held againstthe` Ygear F11s by a spring F20 carried in a recess ink the clutch F11. A leather disc F21, between the gear F16 and the retaining screw F22 fastened in the end of they shaft F13, also tends to rotate the gear F16 with the shaft F13. 4

To the lower end of the shaft F13 isl also fastened a gear` F22' (Figs. 13 and 14) which effects the drive of each of the two cutters 'Which form a part of the cutting mechanism FB as more completely set 1forth hereinafter. The gear F23 drives the idler gear ,F21 (see also Fig. l5) which is rotatably mounted on the pin `F25 fastened in the` housing F11. .At this point in the drive, provisionis made for changing the speed of rotation of the cutters relative .to 'the speed of rotation of theehucks by the following describedv means. The gear F21 .65? drives another idler gear Ff26 which is rotatably carried on a pin F21 mounted` in an arm of the member F28 which is pivoted on the pin F25 and locked into position by a bolt F29 which screws into the housing F11 vand which works in a slot F1o on the other arm of the member F21. Various sizes of gearsmay be substituted for the gear F21' to secure the desired speed of rotation. rlhe member F22 is s o positioned that the gear F 26 meshes with and drives a gear F31 mounted on the short vertical shaft F12' suitably mounted in the housing F11. Near the upper end of the shaft F22 is'fastened a on the horizontal shaft F4 suitably carried in the housing F11. 0n the end of the shaft F40 opposite to the gear F2.9 is fastened a worm gear F11 which drives a Worm wheel F12 fastened on the vertical shaft F13 mountedl in the housing F11. Below the Worm wheel F12 and on the shaft-F'13 is fastened a gear F41 which drives the gear F15 (see also Fig. 19) connected to the larger of the cutters as more fully described hereinafter.

rlthe chuck mechanism includes a mainy member FA1o (Figs. 20, 21 and^22) which is carried on a ball race FA11 mounted in an arm VFA12 of the bracket FA11" mounted on the'base 22. Around the periphery of the upper part of the main member FA1 is cut a gear FA14 which meshes with and is driven by the gear F1 (see Figs. 13, 16 and 18) r previously described. Fastened to the pin FA1" (Fig. 22) which is carried-in the lugs FA'18 (Fig. 20) on the top of the member FA, is a vertical arm FA11 which has at its upper end a` V-shaped engagin finger FA12. To the end of the pin FA15 is fastenedv a horizontal arm FA1" whose end is rounded andv has teeth FA2o which mesh with similar teeth FA21 on the end of the horizontal arm FA22 similar to arm 'FA12 and fastened to 'the end of the pin FA23 (see also Fig. 21) carried in the lugs FA21,on the main member"\FA1. 4vertical arm FA25 similar to the arm FA" is fastened to the pin FA-23 and fastened to the Aupper end of the arm FA21s is a V-shapedengaging linger FA2 similar'to the finger lFA. Through the teeth FA20 and FA21 themotion imparted to pin FA28 mounted onthe member FA10 and .at eachy end to the horizontal arms F`A1"` spring F`A21, fastened at the middle to a and FA?, tends to close the engaging fingers FA1B and FAG toward each other. The engaging fingers FAIS and FA2G are caused to separate as follows: A rod FA29 (Fig. 22) is seated at its upper end in the horizontal arm FA19 being vertically aligned in a lsuitable hole in the main member FA" and has a roller FA pinned in its lower end. rll'he roller FAso rides on the surface of a ringshaped arm FA31 disposed concentric with the main member FAN and fastened to a vertical rod FA32 which is slidably support' ed in the bracket FA13. A spring FA33 (Figs. 21 and 22) mounted around the rod FA32 between the stop FA34 fastened thereto and thebase 22 tends to hold vthe rod FA32 in a lowered position which may be regulated by adjusting the position of thearm FA31 relative to the rod FA32. The angular alignment of the rod FA32 is maintained by an arm FA35 fastened to the lower end thereof and having in its other end a slot which receives the pin FA37 mounted in the base 22. rllhe rod FA32 is raised to force the rod FA29 upward by means of the arm FA, and thereby to cause the separation of the engaging fingers F 18 and FA.l by the action of a cam FA323 fastened to the cam shaft 53. rlhe action of the cam FA38 is transmitted to the rod FA32 by the crank FAS" which is pivoted on the pin FA40 mounted in the base 22 and which has on one arm a roller FA4l riding on lthe cam FAG'23 and on the other arm an adjustable bolt FA42 which engages the rod FA32 to raise the same when so acted upon by the cam FASS. The amount of lift given to the rod FA32 by the bolt FAA*2 may be regulated by adjusting the bolt FA42 in the arm of the crank FA. The contour of the cam FA38 is such that once during every revolution the engaging fingers FA18 and FA2G are caused to be separated and then are permitted to be brought together again by the action of the spring FA. l

As previously stated, the rotation of the chuck FA is stopped after the flare F10 has been cut ofi' to permit the discharge of the same and to permit the indexing of the succeeding glass tubing l() into position. The

f chuck is opened after its rotation has been stopped for the discharge of the flare and is closed again after it has started to rotate.` rlhe chuck is preferably stopped in a predetermined position to permit the proper discharge of the flare F10 and to provide clearance between the engaging fingers FA18 and FA2G and the succeeding glass tubing 10. The position of stopping is preferably with the common center line of the two engaging fingers FA18 and FA26 perpendicular to the path of rotation of the glass tubing 10. The.

stopping of the chuck is effected inthe following manner, A projection FA. (Fig.

20) is fastened to the upper surface of the main member FA10 so that it may be engag'ed by the head of a plunger Ff 44Vwhich works in a corresponding recessin the arm of the crank FA46 which is' pivoted at FAW on the bracket FAH. A spring contained in the recess of the crank FAA16 between the bot tom thereof and the plunger F A44 absorbs the shock when the projection FA43 suddenly strikes-the head of the plunger FAHL which is caused as explained hereinafter. The plunger FA44 tends to engage the projection F A49 fastened to an arm of the crank FA*6 and to thel housing Vwhich encloses a large portion of the cutting olf mechanism above the base 22 and which is not shown in the drawings. The amount of the projection FA43 engaged by the plunger FA44 may-be regulated b`y adjusting the bolt FA5" (Fig. 21) which works in one arm of the crank FA46 and butts against the pin FA51 fastened in the bracket FA52 mounted on the base 22. The plunger FA44 is caused to releasethe projection FA43 by the action of a cam FA53 fastened to the cam shaft 53. rlfhe action of the cam FA53 is transmitted through a crank FA54 pivoted on the pin FA1Y0 roller F 55 riding on the cam FA53 and in the other arm an adjustable bolt FA56 which engages a rod FA57 slidably supported in the bracket FA52 and having a roller FA58 (Fig. 20) pinned in the upper end thereof which engages the beveled edge of an arm of the crank FAt6 to turn the crank FAt6 about its pivot FA4W and thus withdraw the plunger FA from engage- FA43 throughthe action of a spring l and having lin one arm a` mitting the rotation of the chuck through the friction clutch F20 (Fig. 18) previously mentioned. The rod FA57 is normally held in av lowered position by 4the action' of a spring FA59 encircling the rod FA57 and bearing against a stop FA60 fastened thereto and against the base 22. The rod FA" is held in angular alignment by an arm FA61 attached thereto and having a slot FA62 in its end which receives. the in FA". The amount of upward lift of t e rod FA57 may be regulated by adjusting the bolt FAs6 in the arm of the crank FA, The contour ofthe cam F 53 is such that once every rev-A olution thereof the projection FA43 is released from the plunger FA44 to permit the rotation of the chuck and then for a somewhat shorter interval the plunger FA44 is permitted to engage the projection FA43 and so stop the rotation of the chuck to permit the discharge of the fia-re F10 while th@J machine is indexed.

The cutters and mechanism-The flare F10 (Fig. 19) is cut from the tubing by a small cutter FB10 on the inside of the glass tubing 10 and a large cutter FB11 on the outside of the tubing 10. In general the action of the cutters is as follows: The small cutf ter FB is raised up inside the tubing 10 as the latter isvbeing enga .ed by the chuck FA and when the cutter F 1 is level with the large cutter FB11, the two cutters are gradually brought together t0 cut off the flare F1o both cutters being rotated so that the peripheral speed of each cutter is substantially the same as the peripheral speed of the glass surface being cut. .After the Hare F10 has been eut off, the two cutters are separated and the small cutter F'B1" being loweredto permit the discharge of the Hare F1o and the indexing of the succeeding glass tubing 10. The small cutter FB10 is rotated only while in the raised position.

The small cutter FB10 is mounted in the Aupper end of thevertical shaft FB12 which lis supported inthe following manner. The

bracket F15, previously mentioned, supports a tubular member F 13 (Figs. 16 and 18) about which is pivoted.' the sleeve F B14 of the bracket F1315, the sleeve FB14 resting on the bracket F15. `A second bracket F3", previously mentioned, iis fastened below the sleeve FB13 of the bracket F1315. A tubular member FB11 (Fig. 19) carried by the sleeve FB1 provides a suitable bearing for the tubular elevating'member F'B18 which 1s rotatably held on the vertical shaft FB12 at the lower end by the set-screw' collar F1310 and at the upper end by the taper pin collar FB2". The lower end of the vertical shaft FB12 is rotatabl supported in the hub extension F3G of t e gear F35, previously described, the gear F35 being rotatably carried in the lower end of the bracket F37 and being held thereon by the taper pin collar FB21 fastened to the upperI end of the hub extension F35. The vertical shaft FB12 is driven as follows: The gear F35 has two pins FB22 fastened in its lower side and when the shaft FB12 is elevated as described hereinafter one. of the pins FB22 engages and drives a pin FB23 fastened in a collar FB24 mounted on the lower end of the vertical shaft FB12 so that the shaft FB12 and cutter F1310 are rotated. The elevation of the cutter FB1 and the shaft FB11 is effected through the elevating member FB1B by the action of the cam FB25 (Fig. 18) mounted on the cam shaft 53. The action of the cam F1325 is transmitted through a lever FB26 which is pivoted at FB27 to the bracket F1328 fase tened to the base 22 andI which has a roller FB2*1 riding on the cam vFB25. A slot F1530 i in the end of the lever FB2G engages a square lber FB17 to the bracket FB15.

lower end of the member FB13. A spring 'FB33 fastened to the lever FB26 and to a rod FB37 mounted on the base 22 tends to hold the elevating member FB13 in a lowered .of the cutter as previously explained.'

After an interval during which the flare F1o is cut oft' from the tubingt-he small cutter FB10 is caused to be lowered to provide clearance. l r

The large cutter FB11 (Fig. 19)- is .held between the plates FB38 and FB31 which are mounted on the vertical shaft FB1o between the taper pin collar FB11 fastened thereto and the nut F 12 which screws on the end of the shaft FB11. The shaft FB11 is rotatably carried in the sleeve FB43 mounted in the bracket FB44 which is pivotedabout the tubular member FB45 (see Fig. 16) which is a part of the bracket F15 previously mentioned. The shaft FB4o is driven |b-y the gear F45, previously described, which is fastened to the lower end thereof.

In order to provide clearance the two cutters FB11 and F B11 are normally separated but when prepared to cut are permitted to advance toward each other. This action of the cutters is effected in the following manner. On the edge of the4 bracket FB15, which carries the small cutter FB11), is a groove FB11" (Fig. 18) which receives the member FB47 (see also Figs. 16 and 17). A bolt FB1s working in the slot FB4D (Fig. 16) `in the member FB17 fastens the'mem- The head of the set-screw FB5 which screws into the bracket FB15 bears against the end of the member FB" and assists in positioning this member in the groove FB, The inner end of the member FB47 has pinned therein a roller FB51 (Fig. 16) which rides uponv the inclined surface FB52v (Fig. 172) of thewedging bar FB53. Riding on the opposite inclined vsurface FB54 of the wedging bar FB53 is a roller FB53 pinned in the member FB56 which isk held in the groove in the end of the bracket FB*14 by a bolt FB58 working in a slot FB5 in the member FB56 which is similar to the member FB11. lThe head of the set-screw FBG" which screws into the bracket F B11 bears against the end of the member FB56 and assists in positioning the member FB56 in the groove. A spring FB31 fastened to the pin FB12'mounted on the bracket FB11 and to the pin FB11" (Fig. 17) mounted on the bracket F1515 tends to draw the two brackets together swinging the brackets FB15 about the tubular member FB13 and the bracket FB'11 about the tubular member FB45. This action of the spring F1361 is normally prevented by the wedging bar FB53 which separates the rollers FB51 and FB55 but which is withdrawn in the following manner to permit the advance of the cutters FB and .FB11 when they are in position to cut the' Hare F1o from the glass tubing. The wedg ing bar FB53 is slidably mounted in a guiding bracketI FB.84 (Fig. 17) which is mounted free to move horizontally in a bracket wedging bar from between the rollers FB51 and FB but is normally prevented from so doing by the action ofa cam FB69 mounted on the cam shaft 53. The action of the cam FB19 is transmitted through the crank FB1 which is-pivoted at FB71 in the bracket FB15. The crank FB70 has pinned in one arm a roller F1312 riding on the cam FB6g and has fastened in the other arm an adjustable bolt FB?3 which engages the lower end of the wedging bar FB113 to raise the bar when so acted upon by the cam FBsf.. The engagement of the bolt FB73 with the wedging bar FB53 may be regulated by adjusting the positionv of the bolt F1313 in the arm of the crank FB. The contour of the cam FB69 is such that the -wedging bar FB53 is normally held up to separate the brackets FB15 and FB11 until the cutters FB1" and FB11 are in position to act-whereupon the wedging bar FB118 is permitted to be'withdrawn by the action of the spring FB66. rlhe amount of withdrawal of the wedging bar FB is determined by the ositionof the adjustable bolt F 74 (Figs. 1 and-171) which screws in the arm FB15 fastenedto the upper end of the wedg'ing bar and which strikes against the top of the guiding bracket FB11 to limit the downward movement of the bar FB. rl`he amount of withdrawal may be regulated by adjusting the bolt FBMin thearm FB75.

e rlhe horizontal position of the cutters FB10 and'FB11 relative to the glass tubing 10 may be regulated by adjusting the rod FB76 (Figs. 16,v 17 and 17a) which has a head FB" projecting outside the base 22 and which has a threaded portion working in a thread in the guiding bracket FB2" and' whose end .is rotatably held at FB78 in the bracket FBGS. rlhe action of the rod FB76 is such that the guiding bracket FB2i is moved horizontally along the slide FB79 on the bracket FB, the brackets FB15 and FB21 being moved about their respective pivots by the presence of the wedging bar FB53 between their respective rollers. By properly adjusting the horizontal position of the cutters FB1" and FB11 relative to the glass vtubing 10, the upper end of the Hare F10 maybe ymade substantially flush with the main porv tion of the tube, may be turned inwardly or outwardly as shown in Fig. 26. It is believed that an advantage exists in turning the u-pper end of the flare slightly outwardly as ,shown in 0 of Fig. 26 when leading-in wires are loaded through the flare on the usual stem making machines. This also prepares the glass tubing for the subsequent flaring operation. v

The iare F1"7 which is cut from the glass tubing 10 at the position F, when released by the engaging fingers FA1.z3 and FA26 (Fig. 22) falls upon an incline F010 (Fig. l) which is fastened to the'main mmber FA10 of the chuck and which slants toward the discharge chute F011 (Figs. l and `3) to be delivered to a suitable container F012 mounted on vaside of base 22. An air jet F013 (see Fig. 3) which is suitably supported on the base 22 directs a stream-- of air upon.. the flare F1 to blow the flare into the chute F011. In order to deliver the Hare F1`into the container F012, the chute F011 is agitated in the following manner. A ball link F011 (Fig. l) has one end held in a socket F015 on tliechute F011 and the other end held inl an eccentricl 'socket F016 mounted on the upper end of the rod F017 which is rotatably 'held in the bracket F01s fastened to the base 22. The rod F017 is driven from the main driving shaft 26 -by means of the belt F019 (Figs. '3 and'll) driven by the pulley F02o on the shaft 26 and driving the pulley F021 on the rod F011. A spring F022 fastened to the chute F011 and to the bracket F018 tends'to draw the chute toward the base. The-lower end of the chute F011 is pivoted ona pin F023 (see Fig. 3) carried inthe bracket F021 slidably on the base 22 and fastened thereto by the bolt F0251. As the rod F017is rotated the ball link F011 working in the eccentric socket F016 alternately raises and lowers the chute F011 about the pivot pin F023 pro- Vducing sufficient agitation to cause the Hare F10 to pass down the inclined surface of the chute F011 into the container F012.

The v ylanging mecham'sm.-The lowerend of the tubing 10, whichhas previously been heated at position G asv hereinbefore set forth, is flanged by the Hanging mechanism K (Figs. l and 3)'wl'1ieh is located at position H. rlihe flange K1o (Fig. 25) is accomplished by a pencil K11 (Figs. 23, 24 and 25) mounted in a stirrup K12 which is pivoted on the ltwo'standards K13 which are fastened to the cap K11 on the upper end of the ,tubularmember K11. The tubular member Ks is yrotatably held in the elevathe tubular member K15 takes up the thrust between the flange K22 and the adjusting member I 15 when the tubular member K15 is elevated against` .the adjusting member *K15 as mo-re fully described hereinafter.

The upper end of each of the tw-o uprights K23'is pinned one to each side of the stirrup K12y and to the cap K24 which is fastened Ato the upper end of the elevating tube K25. The longitudinal movement of the elevating tube K25 relative to the tubular member K15 causes a movement of the stirrupK12 about the pivots on the standards K11v to bring the pencil K11 through the successive positions assumed in forming Athe flange K1o on the glass tubing'lO. A pin K26 fastened in the cap' K14 andworking in 'a corresponding aperture K27 in the cap K22 serves as a guide for vertical movement of the cap K2A1 relative to cap K14 and also transmits therotative motion im arted to the elevating tube K25, as hereina ter set forth, to the tubular member l 15.

rlhe elevating tube K25 .is caused to rotate by power transmitted to the pulley K28, fastened to thet-nbe K25, by a belt K29 which runs over the idler pulleys K5o and K51 (see also Figs 1 and 3) fastened to the edge of the `base 22 and which is driven by the pulley K52 fastened to the motor 21. The tube I 25 is raised to bring the pencil K11 into operative relation with the glass tubing 10 in the following manner. Positioned on the lower end ofthe tube K25-by the collars K83 (Fig: 24) and K34 is an adjusting member K55 which screws into a horizontal plate K25. The plate K5 is locked on the member `K55 by the set vscrew K55 (see Fig. 24:5) 1 which wedges a plug K55 against the soft metal plug .K39 to force the plugK39 against the thread of the member K25, the plugs K58 andV yK59 being held in the plate K36 in passages at right angles to each other. A vertical guide rod K sliding in the standard K-'has lits\,lower end fastened in the plate K to maintain its alignment during the vertical movement thereof. A roller K11 is pinned toone end of the plate K36 and :s is held against the cam K42, which is fastened on the cam shaft 53 previously described, by the action of a spring K43 fastened to the plate K3G and to the base 22. The conteur of the cam K42 is such that once during every revolution the y elevating tube K25 A is gradually raised through the roller K11 and the plate K25. The pulley K28 carries upward the helical spring K14 resting thereon and bearing against the under side of the flangeK22 which action tends to force the tubular member K1.5 u ward until the thrustA ball race K21 is broug t against the adjust-- ing member K16 where the upward rmovement of the membervK15 is halted while the upward movement of the elevating-tube K25 is continued. lThis further movement of the ythe pencil K11.

tube K25 causes the pencil lK11 to pass through the positions desirable for forming the flange K1o on the glass tubing 10.v The tube K25 is then lowered, the pencil K11 'returned to a normal position and the tubular member K15 also being lowered.

lt sometimes happens that the glass tubn'g l0 breaks while being flanged and the broken off portion of .the tube falls around broken tube be removed from the pencil K11 beforefthe succeeding glass tubing 10 is brought into position for Hanging. To accomplish this removal, there is provided a -stripping bar K45 (Figs. 23 and 24) which is fastened on the upper end of ,the half-- round rod K4G carried in the elevating tube K25 and normally resting on a shoulder K47 therein. A half-round plug'K45 inserted in the upper end of the tube K25 maintains the angular alignment of the rod K45. To the lower end ofthe rod l 45 is fastened a rod K49 whose lower end strikes the head of an adjustable bolt K50 carried in the bracket K51- and so arrests the downward movement of the stripping bar K45 when 'the elevating tube K25 descends after flanging. rlhe pencil K11 thus descends past the stripping bar K15 and anybroken tubing, which may be lodged thereon, is removed. The adjustable bolt l 5 may be regulated to ,alter the position at which the downward movement of the rod 'K49 is arrested. The rod K19 tends to be brought into a loweredposition relative to the elevating tube K25 by the action of a spring K52 which encircles the rod K4 bearing against the aligning member K53 attached thereto and a shoulder K5'2 in the tube K25.

The chuck, lowering and gauging mecham'sm.-The chuck A (Figs. l and 6) holds and rotates the glass tubing l() as it is advanced to each position by the carrier 11 and worked upon by the several mechanisms. The chuck has a main tubular member A10 l(Figs. 6 and 7 which isrotatably held in suitable bearings on the carrier 11 by a collar A11 fastened to the vupper lend thereof. The main member A10 is continuously rotated bymeans of a gear A12 attached near the upper end thereof and driven by the large gear38 previously described. A member A13 sliding inside the main member A10 has attached to its lower end, by links A14, the wedges A15 which hold the tubing 10 through a wedging action against the coni.

It is desirable that this cal surface A15'of the ring A17 which is in serted in lthe lower end of the main member A10. a lowered position by the action of aI spring A18 bearing' against its upper end and against The member A13 is normally held in -a stop A12" fastened in thefupper end of the main member'A1". A collar A20 sliding on the mainl member A10 and rotating therewith engages the member A13 by means of the two l of the rod N10. The crank N18 to a bracket N10 on the base 22 and in its The disc andato a pin N22 fthecam, shaft 53 4o bolts A21 which work in slots A22 in the main member A10 so that when the collar A20 is raised the wedges A17 are raised to release the tubing 10. A groove A20 in the collar A20 receives the rollers A24 mounted on the pins A20 fastened in the arm A20 whose end is pivoted in the member A27 fastened to the tubular shaft 37. When the arm A20 is lifted by the chuck opening mechanism N, the collar A20 is raised relative to the mainmember A10 causing the wedges A10 to be raised to release the lass tubing l0. Upon the release of the c uck opening mechanism N, `-the spring A10 causes the wedges A10 to reengage the tubing 10. To assist in positionthe glass tubing 10 in the chuck a guide sleeve A20 is inserted in the main member A10 and fastened to the stop A10 in the upper end thereof. c.

rlhe chuck opening mechanism has a verti# cal lifting rod N10 (Figs. 6 and 8) which slides in aguiding standard N11 mounted on the base 22. into the split upper end of the rod N10 is screwed-and locked by the set screw collar N12 a support N12 carrying the roller N11 whiehengages the chuck arm A20 tol lift the same when the rod N10 is raised.k

The rod N10 is'raised by the action of the cam N10 transmitted through the crank N10 and the link N17 which connects'A the end of one arm of the crank N15 and the lower end N10 is pivoted at second arm has a roller N20 which is held against thecam N10 by the action of a spring N21 fastened to the irst arm of the crank N10 von the base 22. The cam N1l5 is fastened to and has a contour such that once every revolution thereof the rod N10,

through the crank N10 is raised to lift thek chuck arm A20 and so open the chuck A to permit the glass tubing 10-'to be released while being gauged.

vAs the glass tubing 10 is released athe gauging tube P10 (Figs. 6 and 8) is raised or advanced to receive the flange on the fiber disc P11 to prevent shock or jar to the flange. P11 is fastened to the metal disc P12' which is fastened to the short rod P117 rotatably carried in the flanged member P11. The anged member P11fis inserted in the upper end of the gauging tube P10 and fastened by the set screw collar P10.- The gauging tube P10 is slidably supported in an arm P10 ofthe guiding standard 11 of the chuck opening mechanism and has lower end *thereof a gauging rod P17 which is fastened in the tube P10 by means of the set screw collar P11. The auging rod P17 is raised or advanced by t e action of the spring P10 fastened to the bracket 33 and to one arm of the crank P20which isv pivoted in the bracket P21 mounted on the base 22 and whose other arm is connected by a link v'rod P17 to fastened to the bracket 33y vdetermines the distance 'tubing 10 when the gauging4 inserted in the from its raised or advanced position to gauge the glass tubing 10 by limiting the downward movement of the tubirli 10 while the chuck A is open, the ange 10 resting on the fiber disc P11 which may be rotated inthe flange member P14 by the rotating tubing 10.'. After the chuck A has closed,

the cam P2* releases the roller P20 so that the gaugin tube P10 may be raised by the action of 51e spring P10 but the elevation of the tube P10 is prevented for a time by the presence of the glass tubing 10. When 'the tubing 10has been removed from the disc P11 by the indexing of the carrier 11, the gauging tube P10 is raised by the spring P10 to receive the released lass tubing 10 in the succeeding chuck A t us preventing a shock which might occur should the tubing 10 drop the full distance to the disc P11. In order to permit the making of various lengths of iares, the gauging rod P17 may be inserted to various distances in the gauging P10, a scale P20 being facilitate the proper adjustment of the rod P17 relative tothe tube P10. The length of the rod P17 inserted in the tube P10 the tube P10 will be lowered from the raised position of Fig. 6 and so permits the len h of the flare which will be cut olf to be regulated at this position. The short ends of tubing P27 are removed frornthe apparatus by an air jet P2B (Figs. 1 and 6)*supported in the standard N11' which directs a stream of air upon the tube P10 is in a lowered position, the s' ort end of tubing 10 is thus blown olf the disc'P11 into achute P20 (Figl) which delivers container P20 carried on the'base 22'.V
